STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 591,410, dated October12, 1897.'

' Application fil d November 30, 1896. Serial No. 613,970. (No model.)

'To all whom it may concern.-

Be it known that I, JOHN A. MANGOLD, a

citizen of the United States, residing at useful improvements inadvertising devices designed for street-cars, hotels, post-offices,show-windows, and other places; and it has for its objects, amongothers,to provide a simple and cheap construction capable of use for anyof these purposes, easily operated, and which may be reversed, so thatin case of use upon street-cars or railroads to indicate the stations itmay be easily changed at the end of the route to indicate the stationsor streets in their reverse order. The cards are carried by frames orholders mountedon disks at the ends and the disks mounted upon a shaftor rod passed therethrough, the cards being so mounted as to drop atpredetermined points,-

and in one of the forms of the invention the bards upon both sides of aframe are exposed to view during the rotation of the disks.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form apart of thisspecification, and in which- Figure 1 is a perspective view of myimprovement. Fig. 2 is an enlarged detail showing the slots in the enddisk and the bentpin engaged therein.

Like letters of reference indicate like parts throughout both the views.

Referring now to the details of the drawings by letter, A, Fig. 1,designates the case or box, the front side of which is of glass or othertransparent material.

B are light frames or card-holders arranged between two disks 0, whichare connected by the rod or shaft D, running through the centers of thedisks and supported in the end Walls of the case or box. These frames orholders are constructed to hold the cards E, which may contain anydesired printed matter--such as the names of stations, streets, theadvertisements of various business houses, or others. These frames orcard-holders have each, at each end, a pin F, which are inserted inperforations or holes F in the disks, near the outer edges thereof, sothat they may turn thereon, as upon a hinge. The pins, at one end, areturned at right angles to their length after passing through the holes,forming a substantially. L-shaped pin the projecting portion of which isdesigned to engage a projection G, fixedly attached to the inner wall ofthe end of the case. When the wheel is turned, the bent pin strikes thisprojection and holds the card upright until the card is released by apeg or pin H, attached to the opposite end of the case. When the wheelturns a little, the holder containing the card next to be exhibited willbe drawn down past the pin, so that the card will drop of itsown weightafter being started by the projection G, and thus expose the other sideof the card, while the next card will be brought to view, and is thereheld by the projection H, as was the other one.

The wheel may be revolved in any suitable manner-by hand, byelectricity, or clockwork or other powerbut should be turned quiteslowly, so as to leave the cards exposed a su fiicient length of time tohave them seen.

What is claimed as new is- 1. The combination of the case, of a shaftsupported in the end walls of the case, disks connected by said shaft,card-letters arranged between said disks and having at their ends pinsinserted in perforations in the disks near their outer edges, and acam-shaped projection on the inner wall of the end of the case andarranged in the path of the bent ends of said pins, all substantially asand for the purpose specified.

2. The combination of the case, of a shaft supported in the end walls ofthe case, disks connected by said shaft, card-letters arranged betweensaid disks and having at their ends pins inserted in perforations in thedisks near their outer edges, and a cam-shaped projection 011 the innerwall of the end of the case In testimony whereof I have signed this andarranged in the path of the bent ends of specification in the presenceof two subscrib- 10 said pins, and cards carried by said letters ingwitnesses.

and arranged to drop by gravity after being T started in such movementby the engagement JOHL MANGOLD' of said projection with the bent ends ofthe \Vitnesses: pins, all substantially as and for the purpose M. L.BRANTREE,

specified. J. C. PARKINSON.
